ICE-CREAM-CONE-BAKING MACHINE.

Specification of Letters Patent.

Patented July 18, 1916.

Application filed'July 15, 1915. Serial No. 40,139.

T 0 all whom it may concern Be it knownthat I, WEBSTER A. Tour- Kms, a citizen of the United States, residing at Portland, inthe county of Multnoinah and State'of Oregon, have invented certain new and usefulImprovements in Ice-Cream- Con'e-Baking Machines; and I do hereby declare the following to be a full, clear, and exact, description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyingdrawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to th t class of auto matic bakinglilidllllltfs' in which confection cones are baked from viscousbatter in the annular space formed between the central cone shape core, or male member, of a mold,

hereafter called the core. and the convex conical two part female member of-the mold hereafter called the husk, which together with the core and their accessory. parts forms an oven unit which may be heated by gas burners .or electrical-resistance coils of a well known and widely used (amstruction.

' The drawings forming a part of the application illustrates an electrically heated oven but no preference is expressed or claim made on its use. 1

The object of my invention is to provide a cheap. and etlicient method of baking confection cones, whereby the waste in baking may be materially reduced, and by eliminat iiig' handlabor' the sanitary condition is greatly improved. 7

It is further iny object to increase the capacity of machines of this class by providing a. plurality of charging and disclia.rg ing points so that the period of baking may lie. reduced without increasing the velocity of rotation or reducing the time necessary to charge or discharge the oven.

My invention resides principally in the combination of baking ovens suspended from the. outer ends of spokes, or arms, of a wheel rotating in a horizontal plane, the ends of said arms being adapted to hinge the two part husk oftlie' oven in such manner that it. can be opened and closed at pre-determined points td disehm-ge the baked cone and receive a fresh charge of batter supplied through an opening in the bottom of the husk by a force pump operated by the latch member of the rotating ovens.

erence.

l is a four spoked base spreader to which' In order that the invention may be better understood, attention is now called'to the accompanying drawings, forming a part of this specification and 111 which:

l igure 1 is a side elevation. Fig. Z'is a transverse section of one of the ovens and half section of its support and means of actuation. and Fig. 3 15 a detail plan view I I of the controlling cams.

In all the drawings, corresponding parts are represented by the same numerals of refis attached the supporting legs 2. Upon the center of l is erected the supporting column 3 upon which is journaled the wheel hub '4, with its plurality of radiating arms 5, to which is atlixed the oven support 7. The depending ring 7', which is cast integral with 'theother members 7, forin's'a guide for the vertically moving core 8. This core 8 is adapted to be raised. freeiug itself from the baked cone and may also be depressed to compensate for shrinkage of the cone in baking.

The two pa ri husk 'of the oven 9 is east integral with the supporting hinge members 9 which are hinged upon centers 10, carried by the la s cast integral with and forming a part of t) is a boss cast integral with the ele ments 9 and 9, upon which is journaled the wheels 11.

12 and 12 are converging and diverging cams supported from the frz iinenvork 1414 are wheels, the bearing shafts of which are journaled in the bearing boxes 15 and 15', mounted upon the-front end of the cams 12 and 12'.

1G is an upright staff attixed to 8, and carryingupon its upper end a crossbar 17.

18 is a single acting force pump, the downward stroke of which is produced by the spring 19; 20 is the. piston rod, the upper end of which carries an engagement wheel 21.

2-2 is a. latch by means of which the lower portions of the husk 9 are locked together.

23 is a boss upon the latch 22 which by coming in contact with the stationary pawl 24 unlocks the husk .9; The boss 23 is also adapted tcrengage 21-.

36 isfa container fromfvhich the cones are baked. supplied to the ovens by means of the pipe 25 and the pump 18.

26 is a curved bearing plate adapted to for the viscous batter.

This is 1 lower end of the shaft- 29,-Said shaft 25) being journaled in .the bed plate 7 and bracket-.30. The shaft-29 carriesnpon its upper end apinion '31 which engages the gear 32, said-gear 32 being mounted upon the lower end of the wheel huh 4. source of power to the pulley 28 not shown but may be derived from any suitable source.

33 is a resistance coil of suitable coi'istriwtion supplied with current from any suitable. source, clamped against the baking: members -9 by the plate 34, the whole coil being packed with asbestos to prevent radiaporting column forming. a hearing. a -\\".hoel' tion of heat, and is finished .ing 35.

The operation will he as followsr-J lav]- ing. brought the ovens to a suitable heat and filling the container 36' with hatter of proper consistency, the [low of batter to the ou-ns may be started by operating the pump lShy by an outer eas- 1 hand. Then, as the actuating nmchanisln is started,the top face of the hos-s 22-; engages the wheel 21 on top of the pump plunger 20,

raising the plunger and compressing the spr nglfi. The oven is brought to the posi- .tion 37, Fig. atw'hich point the plunger of .the punip 2021 drops from the boss .23 forcing a charge of hatter inlo the annular space 38, between the core 8 and the husk I '9 fillingthe same up to the ring. 7.-. As the ovens are in constantrotation, they. pass from theopen ng of the paste tube .45 over the smooth surface of 'bearlug platc 2 y means of which the opening 27 in tlnhusk of the oven is closed until tlu-. -hatt er is sullivciently baked not tube fluid, after which the baking eontihued uutil-completed at the point 39, Fig.3, at which point the cr( |s. piece 17 on thetop of the. cm-estali lhxengages. 14 andl by which. means the core 8 is raised verticallysullicicnt to free thr'core from the baked cone,. -oincidont with the raising '0f th'e c0re, the boss 23 of the latch member 22 engaged the stationary pawl .i-l, raising. 22 up and unlocking the o\rn;. at this time, the wheels 11. and .1 I mounted in the bosses'of thehingcd members 2F entered the converging cams'liand 12 b which the husk of the oven is opened at ll), liberating: the baked cone which drops iul'un suitable receptacle, after the cone has dropped. the tingle of the cams 12 and '12 'han ge lo divergence and the oiens close and iuCh, (ton-ipleting the cycle.

It will readily be sccn'that. although I have described a machine with ,a plurality of single baking ovens upon the arms of the rotatingwheel, that 'for a machine of-in The creased capacity the number of tlllXlSll'l'll) be increased and a plurality of ovens placed.
